Remove filters. You will not harm your tub by operating it with the filters out.

Add one full bottle of Spa Marvel Cleanser into the existing water. Spa Marvel Cleanser performs much better in warmer water than in colder water. Run jets on high for at least 1 hour and then allow to circulate for an additional 23 hours. It is important that the Spa Marvel Cleanser circulate in the spa water. If the pumps are not on, the water is not circulating. If your spa does not run continuously, you may need to leave the Cleanser in for longer periods of time. i.e. if your spa circulates 12 hours a day, leave the Cleanser in for 2 days. 12 hours X 2 days = 24 hours of circulation. It is OK to leave the Spa Marvel Cleanser in the spa for longer than one day.

Do not use the spa during the cleansing process.

Spa Marvel Cleanser on its own does not foam. If you experience massive amounts of foam it is a result of contaminants that were built-up in the tub’s plumbing being removed and reintroduced to the water.

Drain the old water out. Flush each jet with fresh water, clean and thoroughly rinse the tub, doing the best you can to remove the old water. Repeat before every drain and refill.

Clean both sides of the spa cover using a cover cleaning product available from your professional spa store. If the cover is cracked or torn, we recommend it be replaced. The inside of spa covers have been known to harbour mould and bacteria, all of which drip from condensation through the cover back into the spa water.

If you have a brand-new spa we do encourage you to use the Spa Marvel Cleanser to remove the residues from the manufacturing process. However many new hot tub owners are anxious to get using their spa and would prefer not to start out with the cleansing process. Many new spa owners also often experience extremely high bather loads during the first few weeks of ownership as all of their friends, family and neighbours come to experience their new hot tub. Remember that 4 people in a hot tub are equivalent to 400 people in a pool. This excessive use often dictates the necessity for a water change after only 1-3 weeks of using the spa.
